Yure and Axel were there, laying under the ceiling of the tree house. Yure was a blue fat cat, with an absurdly long tail and a mane around his neck. Axel was a regular tiger. Both were cubs. There wasn't a lot to do and both felines were bored. It was hot that way, to make matters worse, and Yure wasn't tolerating his marbles boiling inside his diaper anymore.
- Dude, this sucks... - he said, unbuttoning his hybrid diaper.
	Axel looked at Yure and decided to do the same, removing the tapes from his plastic diaper.
	- Yes – he said. - It's hot and boring here. It must be a torment for you, since you are almost obese.
- Watch your language, pharisee – responded Yure, sitting on his nude fat ass.
- Forgive me.
- I'm gonna drink water... - Yure got up, walking his sweaty self to the kitchen.
- I'm going too... - said Axel, getting up soon after.
	The tree house. was quite big and had four rooms, plus piped water. But not electricity; if it had, the cubs could at least play turning the lights on and off or trying to balance the interrupters between “on” and “off”.
	Yure got the cup and filled it with water from the tap; the pipes were good enough and he trusted the treatment the water received. He drank cup after cup, making his big belly look even bigger. Axel knew what that implied: Yure would tell him to the same. Before the other feline could ask, Axel started to fill another cup and drink repetitively. After two minutes of filling cups and drinking the contents, both cubs had their bellies fit to burst.
- I know what we are gonna do – said Yure.
- Pee-holding contest? - asked Axel.
- No. When the water make it's way through us and gone to the bladder, we will play wrestle. The objective is to make the other pee. Whoever pees first, loses.
- That is, a pee-holding contest – Axel smiled.
- Think as you wish.
	The naughty cubs went back to the room and laid there, waiting for their bodies take care of the rest. During forty minutes, they chatted about silly things, such as weight gain, diapers, urine and other males of their age. Axel didn't mind talking about males, even if he was more interested in females. But, since Yure was very interested in the subject, he decided to wind him up.
- I want to pee already – said Axel.
	Yure rolled and looked between Axel's legs. The tiger's penis wasn't erect yet.
- Be strong and hold a little more – he said. - When you have a rock-hard erection, then you will be desperate.
- Same goes for you? - asked Axel.
- Same goes for me.
	And both laid still. Time passed slowly. Yure was playing with his thing, looking at Axel from time to time, to feel inspired. Axel noticed.
- Desperate? - he asked.
- Desperate enough. But not even close to my maximum capacity – answered Yure.
- What is your maximum capacity?
- Last time I measured, it was one liter.
	Axel's eyes went wide.
- One liter? - he asked, amazed. - I die from pain at 800 ml!
- It hurts a lot, I must admit – said Yure, with a proud smile. - But I'm strong.
- Someday we will see if I can beat your record...
- I doubt it, but think as you wish.
	Time dragged by. The cubs were uncomfortable with the growing tension in their bladders. Yure was still soft, but Axel started to develop an erection.
- I think I'm ready... - he said.
- Then we can start – said Yure.
- No, not yet – Axel pointed to Yure's penis.
	Yure looked down and noticed that he wasn't erect yet, despite already needing to piss with certain degree of urgency.
- Are you sure you can wait? - he asked.
- Yes, I'm sure – said Axel.
	Yure shrugged and waited a little more. After a few minutes, Yure started to become hard.
- I'm desperate... - whined the cat.
- What about me? - asked Axel, strangling his thing with both hand-paws.
- Let's end this quick – said Yure.
- Yes, sir... - Axel got up and got in position.
	Yure did the same. Both cubs became even harder, knowing that they were about to grab each other with the secret objective of getting themselves drenched in urine.
- Now! - Yure yelled, hugging Axel by his wait and trying to take him down.
	Axel was surprised and grabbed Yure by his neck, bending his body over Yure's. Yure was very heavy and strong, soon lifted Axel from the floor and threatened to jump:
- If I jump forward, I'll fall over you!
	Axel through quickly. He kicked right on Yure's underbelly, hitting the felines distended bladder. Yure got close to losing! Axel kept kicking, time after time, until Yure was forced to release him. Yure jumped back, getting distance.
- What a dirty trick from you! - said Yure.
- Tell me about the obvious – said Axel, showing his tongue.
	Yure ran against Axel again and jumped over him, taking him down. Their bladders pressed against each other, but Yure not only had experience and was older, but he was also very heavy.
	The pressure over Axel's bladder was disturbing and the little tiger began to squirm his thighs, forcing them against each other, rubbing them to keep the control. His penis pulsed with the muscle effort to keep the bladder under control. Yure was becoming too aroused, loving to fight not only against Axel, but against the forces of nature. Every time when his bladder had a frustrated contraction, he felt pleasure shivers run his spine up, to the brain, and down, to the penis.
	Axel had not given himself up and, bending the knee and positioning it between himself and Yure, flipped suddenly, becoming on top, with his knee between his friend's chest and belly, with the leg pressing the underbelly. Yure whimpered, but kept his bladder under control, but his lust was threatening to rebel. Axel didn't like to hold his pee as much as peeing on things and other animals. He was going crazy to release his bladder's contents over Yure and have his friend's piss released over him.
- Give up! - Axel tempted.
- Never! - Yure gave his most dramatic answer.
	Yure forced himself up, even if still under Axel, which demanded him a lot of strength. Plus, the effort pushed the cat's bladder against Axel's leg, adding even more pressure to the muscle that got fuller at every passing minute. Yure's penis pulsed and touched Axel's butt as the cat slowly got into sitting position. When Yure was sitting, he broke free from Axel's grapple and hugged him, now that Axel was sitting as well. The movement seemingly purposeless had the objective of pressing Axel's leg against the body; the leg was still between them and Axel had to keep it bent. The hug became tighter and tighter and Axel began to whimper, with his articulations in pain.
	Yure released Axel and got up. His bladder was hurting and heavy. Axel got up soon after, massaging his leg and forcing his thighs together. The erections of both felines pulsed with their heartbeat, that reverberated in the whole body, even on the liquid that they held with vigor.
	They ran against each other again and grabbed each other by the arms, one trying to take the other down. They grunted and sweat, their fur becoming wet with excretion of sweat, they made wild noises and panted. They were loving the game, even if they knew that the disaster was imminent: the sphincters of the cubs weren't mature enough to endure such effort. Even if the upper half of their bodies was sincerely trying to continue the fight, their bodies fought an inner battle from the waist line below. Their legs, divided between the task of balancing the body and remain tightly squeezed, couldn't relieve the pressure that the contractions from the muscles withing forced over the bladder. The liquid was pushed against the sphincters, that were pressured to remain shut, but they were spending energy fighting and the contractions from the rest of the body made their task of not relieving themselves too hard.
	The cubs shivered, moaned, every time they managed to keep their urine in after a strong contraction. Tremors of pleasure and pain run through their bodies, causing goosebumps, hardening the nipples, making the skin blush where it could be seen, inciting obscene sounds.
- I can't stand it anymore, Yure – said Axel, loosening his grip.
	Suddenly, Yure used the occasion, turned Axel and threw his body over Axel. Yure sat on Axel's butt and the fall made the tiger lose a few droplets of urine, making a small puddle under them.
- Do you know what I'll do now? - Yure asked.
	Axel had a faint idea of what was about to happen. Yure adjusted himself and thrust his erection inside Axel's rectum. Because Axel was small and not so fat as Yure, it wasn't so hard to give him that kind of pleasure, even if Yure's “pride” was more like a “modesty”. The movement began, each thrust of Yure against Axel made the liquid inside the cat shake. Bit by bit, despite Yure's efforts to keep himself under control, urine leaked in sporadic droplets into Axel. The little tiger felt the liquid go inside him and dribble deeper, tickling him.
	Axel, at each thrust, lost more urine. He tried to control himself, because he wanted badly to wet Yure with his liquid, but it seemed liked Yure wasn't willing to wait for that. Suddenly, Yure stopped.
- Flip your belly face-up – the cat said.
	Axel rolled cautionsly, so that he didn't have to take Yure's penis off himself. Yure pressed Axel's peen, pushing him against the tiger's belly. He did a small massage. Yure was under great pressure, his legs shaking and, no matter how tight they pressed together, urine escaped to Axel's inside in sudden, but short, spurts. Axel purred loudly and smiled like an idiot. Yure resumed the movement. Every time when Axel leaked more urine, his penis position, kept by Yure, directed the flow up, to his his belly.
- I can't stand any longer... - Axel whined, as excited as Yure was.
- Stop moaning like a bitch, Axel... - Yure suggested. - Be strong.
	Yure began to lose even larger amounts of urine. He was feeling too much pain trying to hold it all in.
- Time to end this; I won, anyway – he said.
	Yure began to pee, with full force, into Axel's rectum. While peeing, however, Yure was still moving back and forth, getting himself even hornier. Axel was so horny that he thought he would explode. “This can't be good for my health...”, he thought. Suddenly, Yure stopped urinating and grunted, having a dry orgasm inside Axel. The tiger was a bit disappointed, but, in the end, Yure was a cub as well. Satisfied, Yure resumed the urination. It was so much piss, that Axel's anus overflowed. It was hard to believe that the cat's bladder could hold just one liter of liquid.
	Axel shooed Yure's paw away and started to masturbate, despite the fact he was still urinating. When his urine flow stopped, he had his orgasm. Yure pulled his penis from Axel's rectum and laid down. Both cubs were tired.
- I couldn't even piss on you – Axel said to Yure.
- Don't worry; bladders are easy to fill... - Yure answered.
	After resting, the cubs got up. They looked at each other.
- You need a bath – Yure said.
	Axel laid down again. Yure laid beside Axel and began to lick him, cleaning his fur. Axel closed his eyes and enjoyed the sensation.
- It's hot today... - Yure complained.
